Before you start developing applications on MapR’s Converged Data Platform, consider how you will get the data onto the
platform, the format it will be stored in, the type of processing or modeling that is required, and how the data will
be accessed.

A MapR Expansion Pack (MEP) provides a set of ecosystem components that work together on one or more MapR cluster versions.
Only one version of each ecosystem component is available in each MEP. For example, only one version of Hive and one version
of Spark is supported in a MEP.

As of Sentry 1.6, the database storage model is the preferred method for storing privileges and roles. When you configure
Sentry to use the database storage model, it also includes a service that is managed by Warden.

Integrate Sentry with other ecosystem components to enable those components to use Sentry authorization. You can also
integrate Sentry with Hue in order to use the Hue Security application to manage Sentry privileges and roles.

Starting with MapR Expansion Pack (MEP) 6.0.0, MapR Object Store with S3-Compatible API (MapR Object Store) is included in MEP repositories. To fully benefit from the MapR Object Store, it is important to understand what the
MapR Object Store is and how it works, how to authenticate it and perform bucket operations.
